RECOIL SELF-COCKING GUN.

SPECIFICATION forming part of Letters Patent No. 426,916, dated April 29, 1890.

Application filed June 24, 1889.

T0 aZl whom it may concern:

DELOS R. BRAOE, both of Hannibal, in the county of Marion and State of Missouri, have invented a certain new and useful Improvement in Recoil Self-Cooking Guns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a device for cocking hammerless guns by the recoil of the percussion when the butt is struck against the ground; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side view of a gun to which our invention is attached and which has no visible hammer or means of cooking. Fig. II is a vertical section of the stock of the gun, and shows the self-cocking devices inclosed therein. Fig. III is an enlarged vertical section of the stock, and shows the adjustable attachment of the trip-rod to the operating recoil-cap and the position of said cap on the butt of the gun, it being shown in inoperative position in full lines and in operative position in broken lines. Fig. IV is an end View of the operating recoil-cap, and shows the attachment of the trip-rod to its center and the rivets for securing to said cap the spring-hooks which help to hold it in position and aid its elastic movement. Fig. V is a transverse section taken on lineVV, Fig. III, and shows the stay-plate that limits the ac tion of the trip-rod both when cooking and on its return. Fig. VI is a transverse. section taken on line VI VI, Fig. III, and shows the tube in which the operative trip-rod works and the pins with which the spring-hooks engage. Fig. VII is a perspective view of the recoil-cap removed from the butt of the stock of the gun. Fig. VIII is an enlarged longitudinal View of the operative trip-rod, and shows the forks which respectively cook the respective hammers. Fig. IX is an enlarged vertical section taken on line IX X, Fig. XI, showing the hammer uncooked. Fig. X is a like view on the same line, showing the ham- Serial No. 315,349. (No model.)

mer cooked; and Fig. XI is an enlarged staggered section taken on line XI XI, Fig. IX, and shows the breech of a double-barrel gun, the two hammers, and the lugs on the lower arms of the hammers, against which the forks of the operating trip-rod Work.

Referring to the drawings, 1 represents the stock, 2 the barrels, 3 the breech, 4 the lock, 5 the hammer-spring that gives impulse to the hammer when tripped, 6 the pendent catch-pin with which said spring engages, and 7 the triggers that trip the hammers, all and several usual parts of a (so-called) hammerless gun (that is, a gun in which the ham mers or other percussive elements are hid within the boxing of the stock.)

8 represents the percussion-pin, the head 9 of whichworks in the spring-chamber 10 in the breech and receives its reactionary impulse after percussion by the spiral spring 11 in the forward end of said chamber, and under the influence of the hammer 12 the needle or projectile-pin 13 (an integral part of said percussion-pin) is rapidly projected through the firing-tube 11 in said breech and forces the cartridge in the barrel with which it engages.

The hammer 12, which is secreted in the I lock-chamber 15 in the stock, has bearing on the pivot-pin or trunnio'ns l6, and pivotally connected with a forwardly-projecting swell 17 of said hammer and hanging pendent therefrom is the catch-pin 6, with which the main hammer-spring 5 engages to enforce the striking ofsaid hammer in firing when it is tripped by the trigger.

The lock is of usual construction, and so need not be here specifically described.

We will now proceed to describe the means by which the hammers to both barrels are simultaneously cocked, or when one is already cocked, without disturbing the same, the other is also cocked.

18 represents a sliding metal cap (preferably of sheet metal) that fits loosely over the butt 19 of the gun-stock. The rear end of said cap has a central inward bend, forming a recessed chamber 20, through the perforate center hole 21 in which the rear screw-threaded end of the operative trip-rod 22 projects and where it is secured by the screw-nut 23 within said recessed chamber and the jamnut 24 within the cap, which together rigidly hold the rear end of said trip-rod to said cap, so that it of necessity moves with the cap.

25 represents a bifurcated chamber or double-socketed boxing in the butt of the gunstock, constituted'of a rear or outer cut-away 26 and two inner socket cut-aways 27 2'7 in conjunction therewith. A sufficient amount of the stock-timber intervenes between the said sockets for the formation of the central longitudinal trip-rod chamber 28 through from the breech of the bifurcated chamber 25 to the lock-chamber 15. This triprod chamber-is capped at the rear end by the buffer stay-plate 29, which reaches across said timber-section from socket to socket, being secured thereto by the screws 30. The said stay-plate is provided with a hole 31 in the center, through which the operative trip-rod 22 works.

32 represents an enlarged outer terminal of the perforate trip-rod chamber .22 immediately inside the stay-plate, within which enlargement are located the screw-nut 33 and its screw jam-nut 34 on the threaded portion of trip-rod 22.

35 represents atubular sleeve that is tightly seated within the perforate trip-chamber 28 immediately beyond the enlarged outer terminal of said chamber, so as not to interfere with the necessary movements of the nuts 33 and 34. as the trip-rod moves while cooking. The said sleeve acts as a stop to limit the forward movement of thetrip-rod by the jamnut .34 buffing against said sleeve, while the back action of said trip-rod is arrested by the nut 33 coming in contact with the buffer stay-plate 29.

36 represents the bifurcated forward end of the operative trip-rod, the individual forks of which respectively come in contact with the projecting lugs 37 37 on the lower limbs of the'respective hammers when the gunis set down or slightly struck against the ground, as a soldier does in'obedienceto the com- "mand order arms, so that when said cap and trip-rod slide from the position shown in full lines to that shown in broken lines in Fig. 3 the forks strike against the projecting lugs 37 37 on the lower limbs of the respective hammers and drive said lower limbs forward,

and the hammers, turning on their pivots, in consequence retire their striking ends from the percussion-pins and place them instantaneously at fu11-cock from the position shown in Fig. IX to that shown'in Fig. X. Now it will also be seen that should one of the hammers be cooked and the other uncooked, but, while there is no present cause to fire, it is desired to take time by the forelock and be ready for all emergencies when it may be required to discharge both barrels in quick succession, then the lug of the hammer that is cooked offers no-obstruction to the action of the other fork of the trip-rod, which, when it cooks its respective hammer,-both forks will assume the position shown by the one in the sectional view in Fig. X. a

38 38 represent two spring hook-rods whose angle ends are secured to the inside of the butt or end of the sliding cap 18 by rivets 39. The hooks 40 of said spring-rods embrace the pins 41, that pass through the stock and through the sockets 27 of the bifurcated chamber 25 when the cap 18 is in its normal position, as shown in full lines in Fig. III, with the cap extended to the rear of the butt of the stock, and then said springs by their hook attachment retain the cap in said position until it is grounded, as stated, when as the cap and tripping-rod are forced into their operative position to again affect the cooking of the hammers the spring-hooks are forced forward, as shown in broken lines in the same figure; but as soon as the hammers are cooked and the weight of the gun is lifted from the ground then the pressure of said spring-rods 38 throws thecap 18, drawing the trip-rod with it back into their normal position; but said return action does not uncock the hammers. The forks of the trip-rod have cocked the hammers. The usual looks, as shown, retain. them in cock, ready, when the triggers are drawn and too operative movement of the device while cock- Second, the reactionary functions of said springs, which, after having been thrown forward duringthe action of cooking the hammers into the positions shown in broken lines'in Fig. III, then exert a co-operative inclined pressure against the catch-pins 41 and spring the cap and trip-rod back to their normal position ready for future action in cocking, which action could not take place without said previous return of the said cap and triprod to their normal position ready for subsequent action. The flange of said cap when thus sprung back again fits snugly to the stock it embraces, and the spring-hooks, as they 7 again embrace the catch-pins 41, hold the rear butt of said cap firmly in its rear projection from the butt of the stock until it is again impelled forward by grounding or otherwise striking the butt of said cap against any object to effect the cooking of the hammers.

Third. We now come to the anti-kicker functions of the springs. It will be. seen, as

stated above, that after the 'automatic'instantaneous cooking of both hammers and subsequent reprojection of the cap 18 by the impulse of the springs 38, whose hooks are then looked around the catch-pins 41, the butt of said cap then forms a spring anti-kicker cushion that rests against the shoulder of the sportsman when firing, and that effectually disposes of the recoil-kick from the firing of the gun.

We claim as our invention- 1. The combination of the pivoted hammer provided with the actuating-limb, the projecting lugs 37 on said limb, the sliding cap 18 on the butt of the stock, and the operating trip-rod having a bifurcated head, said triprod being secured to saidsliding cap and arranged, when said cap is slid in on the stock for the bifurcated trip-rod, to strike the lugs 37 and cook the hammers, substantially as described, and for the purpose set forth.

2. The combination of the invisible pivoted hammer provided with an actuating-limb, the projecting lugs 37 on said limb, the sliding cap 18, the bifurcated trip-rod secured to said cap, the tubular sleeve 35, secured within the perforate chamber 28 in the stock of the gun, the said stock being provided with a bifurcated chamber 25, the stay bu flier-plate 29, secured at the breech of said bifurcated chamber, and the screw and jam nuts seated on the screw-threaded shaft of the trip-rod, that limit the play of said rod by buifing against the plate 29 on the one hand and against the tubular sleeve 35 on the other hand, substantially as described, and for the purpose set forth.

3. The combination of the invisible pivoted hammer provided with a pendent actuatinglimb, the projecting lugs 37 on said limb,'the cap 18, that slides on the stock, the bifurcated trip-rod secured to said cap and whose forks trip said lugs 37 on the actuating-limb of the hammers to cook said hammers, the springrods 38, provided with hooks, said rods at their fast ends being riveted to the sliding cap 18, and the catch-pins that pass through 5 and are seated in the stock of the gun, against which pins the said springs ride and their hooks engage, substantially as described, and for the purpose set forth.

4. The combination of the invisible pivoted 5o hammer provided with a pendent actuatinglimb, the projecting lug 37 on said limb, the

cap 18, that slides on the stock of the gun, the bifurcated trip-rod secured to said cap and whose forks trip said lugs 37 when said cap is slid on the stockto cock said hammers, the percussion-pin 8, that the hammer strikes when tripped to fire the cartridge, the springrods 38, that are riveted to the sliding cap 18, the catch-pins 41, against which said springs ride and on which their hooks catch, the said springs being arranged as equalizers to facilitate the sliding of the'cap on the stock, as reactionary springs to throw back said cap and the trip-rod it carries to its normal position of rest after cooking the hammers, and also as a spring-backing to cushion the sliding cap against the shoulder of the sportsman to dissipate the recoil when firing, substantially as described, and for the purpose set forth.

5. In a fire-arm, the combination of a contractible stock, a hammer, and a connectingrod between the stock and hammer, whereby the latter is cooked by the recoil ot' the gun, substantially as set forth.

6. In a fire-arm, the combination of the hammers, the operating trip-rod, and the cap on the stock, said rod having a bifurcated end the members of which engage directly with the respective hammers, as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in the presence of two witnesses.
